a solid 550-600W PSU from a quality vendor such as Seasonic, XFX, Corsair (except th CX series) or Antec should work unless you will be overclocking or adding another GPU down the line. Here is a reference that has a recommended chart and a PSU calculator:

A high quality PSU (ex.: tier 1 or 2 on EggXpert's list) over 400W would be enough for just about any high-end single-GPU system. For slightly lesser quality PSU (tier 3), you would probably need to bump that to 500W. For more "average" PSUs (tier 4), another bump to ~600W might be necessary for longer-term stability.

A 750W CX might be a little tight for a pair of 280X: you might end up pushing it to ~90% if you run things like Furmark. So you might want to step it it up one notch.

Would a OCZ Fatal1ty 750W be ok? Would I get 100%? Also you think this is a good setup for call of duty games, cuz I would play such fps games...

Most half-decent PSUs can go to 100-110% load at least for a while when they are fresh off the assembly line. The reasons for not recommending running even good PSUs at that high of a load is due to aging and efficiency: PSUs are usually most efficient between 40% and 70% load while aging will degrade the PSU's output quality over time and this tends to occur more quickly with increased load.

As long as you do not plan to run extended Furmark burn-ins, 750W should be enough.
